Learn about our Bulkheads and Stop Logs

Bulkhead Gates and Stop Log Panels are mainly used to isolate a waterway structure for maintenance. These gates or panels are installed and removed under balance head conditions with a crane. Commonly, a Bulkhead Gate refers to a single panel gate and Stop Logs are furnished in multiple sections to reduce required lifting forces.

When it comes to Bulkhead Gate design, a reinforced gate leaf with bearing pads and rubber seals is the basic construction. Both types require lined guide slots in the walls to hold them in place and seal. A lifting beam with engaging hooks is typically used to place and remove stop logs. A Bulkhead gate may use a lifting beam or connect directly to a wire rope hoist. Filling valves may be included in these gates to balance water pressure before removal.

Bulkhead gates may be stored in the guides if space allows. Stop logs are usually stored out of the guides wherever ground space is available.
A Draft Tube Gate is a form of bulkhead gate for sealing off a draft tube from downstream pool.
